I have just received an Soundtraxx DSD 050 K-36 no.484. I instaled It in my IHC mike tender for now,to be moved to my Rivarossi Y6B at an later time.It did not come with an Chaff Cam for the drivers,Can an chaff cam be made off the axles of the tender?? And how does this work?Do these wires(BROWN) have to be hooked up?To get the chug? I'am useing an Bachman EZ command DCC,the bell,whistle,air,couplers ect,ect all work just fine,I ave found out that you can't set CV's on this unit.(I know get a better DCC systeam).all help will be useful!Thanks JIM
